1998 Chevrolet Tahoe ProblemsCheck Engine Light and Misfire Due to Stuck Fuel Injectors
One or more fuel injectors may become stuck closed causing an engine misfire and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.
1998 Chevrolet Tahoe QuestionsWhy does my transmission not want to shift from 2nd to 3rd (1 answer)
Ok..so 1st thing I did is transmission tune up new filter, 2 selinoids , gasket and new fluid and no change.
What else can I check or so?
I changed practically everything that could be wrong with my heat but when I bought my truck the heater control valve had to be replaced but didn't have the money for it so I took it out and now I don't have heat at all.
